[T3] Two Tests

Good to know about the mounting issues of the new style VR's.

So, you re-installed the one brain you marked "bad"?

This afternoon I decided to get off my butt and do 2 things that I had been 
postponing for way too long.

First, I needed to replace the voltage regulator on my ratty daily driver, the 
beige '73 Square. I've been getting those loud clicks from the old one that 
always preceeds their death. Best to change it now, before any harm is 
done. This was my chance to try one of the new Bosch electronic VRs.

I havn't been too excited about these, because they have a large upper shell 
which is entirely at generator output voltage. Seems like an invitation to 
shorts.

In the process of installing this new VR, I ran across a few other problems 
that I think are equally troublesome.


Once installed, it seems to regulate well, but I'll need more experience with it 
to know better.

The second task was to go thru my stash of FI brains and test a few '73 048 
brains, to make sure I had some that seemed good. I think I came up with 5.

I pulled out the one in the car, that had been working fine for the last 3 
years, and tried each of my others in turn. Those tests were short, but my 
original '73 still seemed to run extremely rich. So I'll set that one aside, 
marked as bad. Apparently there is something that can go wrong with that 
version. While testing, I noticed that this last generation has 2 boards, an 
upper and lower. If I'd noticed that before, I'd forgotten. I'll have to look at 
some earlier versions to see when that started, but I don't think the ABCD 
versions were that way.

When I was finished, I reinstalled the one that has been working well for the 
past 3 years.
